Yes to both questions: Roller Screws have been produced since the early 1950's and their utmost reliability is the reason why they are prefered when repair or replacement is very costly or even impossible, such as in Space or Nuclear power plants or even Medical Prosthetics.

Definitely! Roller Screws Actuators are lighter: They have a smaller footprint and a larger power density and their maintenance costs are very minimal. Just a small caveat: Hydraulic actuators handle compressive load better than tension loads: Roller Screws behave just the opposite way! We would gladly help you to shift.

We make Screws with diameters ranging from 3.5mm ( about 1/8" ) to 150mm ( about 6" ) and lead from 1mm to 30mm. We have even designed and manufactured Roller Screws with a lead of thread of less than 25 Microns (0.001 Inch).
